| Abstract | The aim of this study was to evaluate occlusal and orofacial myofunctional characteristics in children with primary dentition and anterior open bite, before and after removal of pacifier sucking habit. A dentist checked anterior open bite, overjet and upper intercanine distance and a speech therapist evaluated posture and tonus of lips and tongue, cheek tonus, swallowing, breathing and speech of twenty-seven 3-5 year-old children at baseline and 3 months later. Habit removal propitiated a mean reduction of 1.97 mm on anterior open bite (P < .001), promoted improvement of lip posture (P = .03), favored nasal breathing (P =. 008) and reduced the occurrence of tongue interposition during swallowing (P = .008). Lack of proper tongue rest posture was capable of preventing spontaneous correction of anterior open bite (odds ratio 17.50). |
